Sodium propionate is colorless transparent crystalline or granular crystalline powder with a slight odor.Salt is a colorless crystal with hygroscopicity.It is soluble in water and ethanol, with a solubility of about 100(15ºC) in 10% water and a pH value of 8.5~10.5.It has a wide range of antibacterial effects on mold, yeast and bacteria, and is most active in acidic pH.
Used as food preservative, suitable for cake as preservative and bread as anti - mildew agent.Sodium propionate is almost nontoxic to humans.The amount of calcium propionate in food is the same as that in propionate.The maximum allowable concentration for use in cosmetics is 2%(as propionic acid).The propionic acid was neutralized by sodium hydroxide.
1 Sodium propionate liquid wet acid preservative, its bacteriostatic effect is affected by the environment PH.The minimum inhibitory concentration was 0.01% at PH5.0 and 0.5% at PH6.5.In acid medium, the inhibition of various kinds of mold, aerobic bacillus or gram-negative bacilli by strong.It is effective in preventing the production of aflatoxin, but has little effect on yeast.In addition, it also ACTS as a food preservative.
2 Make in tanning agent, in order to improve the alkali resistance of leather and tanning uniformity.
3 Sodium sulfate is also an acid food preservative, whose bacteriostatic effect is affected by the pH value of the environment. The minimum inhibitory concentration was 0.01% at pH 5.0 and 0.5% at pH 6.5.In acid medium, it has strong inhibitory effect on all kinds of molds, gram-negative bacilli or aerobic bacillus.It is effective in preventing the production of aflatoxin, but has little effect on yeast.In the food industry, it can be used for the preservation of pastries with a usage of 2.5g/kg(in terms of propionic acid, the same below);The maximum usage is 50g/kg in 3% ~ 5% aqueous solution.Also can make the mildew agent of feed.
4 Food, feed and anti-corrosion and anti-mildew agent.The general additive amount is 0.1-0.3%
5 Cosmetic preservatives.To mold, yeast and has a wide range of antibacterial effects.The antibacterial effect is especially obvious in acidic hydrolysates.The amount added to cosmetic products is usually no more than 2%.Insecticide, anti - mildew agent. Determine transaminase.To improve the alkali resistance of leather and the evenness of tanning.
